Where To Start
A blog is very similar to a website and you can use the same techniques choosing your domain name and you host. There are plenty of free blog sites available online but they often have advertising you are not receiving money for and are limited in the amount of features they offer. The misconception about blogs is that they are for writing your daily thoughts or sharing interesting information and websites you find on the internet. They might be great for these things but did you know you can create a fully functional website in half the time using a blog. All of the extras listed in Design and Enhance can be done with a simply plug-in or widget without having to buy software or know code.
First I still recommend buying a domain and a host to create your blog. It is more professional and it is a small investment with large returns. If you are hesitant just purchase it for a year and see the amount of people that are impressed by your blog. Honestly, if you design your blog correctly most guests that visit your website will not realize that it is a blog and think you spent thousands hiring a web design company.
